* include/atomic.h (atomic_compare_and_exchange_val_acq): Add comment.
Don't define if __arch_compare_and_exchange_val_32_acq is not defined.
(atomic_compare_and_exchange_bool_acq): Add comment.  Don't use
__oldval variable in the macro, since it might be macro argument.
(atomic_decrement_if_positive): Initialize __memp, remove setting
of non-existent variable.
(atomic_bit_test_set): Cast 1 to __typeof (*mem) before shifting.
* sysdeps/ia64/bits/atomic.h (atomic_exchange_and_add): Implement
using atomic_compare_and_exchange_val_acq.
(atomic_decrement_if_positive, atomic_bit_test_set): Define.
* sysdeps/s390/bits/atomic.h (__arch_compare_and_exchange_val_8_acq):
Renamed from...
(__arch_compare_and_exchange_bool_8_acq): ... this.
(__arch_compare_and_exchange_val_16_acq): Renamed from...
(__arch_compare_and_exchange_bool_16_acq): ... this.
(__arch_compare_and_exchange_val_32_acq): Return old value.  Renamed
from...
(__arch_compare_and_exchange_bool_32_acq): ... this.
(__arch_compare_and_exchange_val_64_acq): Return old value.  Renamed
from...
(__arch_compare_and_exchange_bool_64_acq): ... this.
(__arch_compare_and_exchange_val_32_acq): Use __typeof for local
variables types instead of assuming int.
Change prefix of local variables to __arch.
* sysdeps/generic/bits/atomic.h (arch_compare_and_exchange_acq):
Remove.
(atomic_compare_and_exchange_val_acq,
atomic_compare_and_exchange_bool_acq): Define.
